OK - I've been all over. Heres the pool & problem. 25,000 gallon liner. 7 year old pool and hayward 2.0 hp. the pump sits 3 feet above pool. One skimmer, One main line. Both come up and merger to jandy valve in front of basket/pump. For a while I was getting small amounts of bubbles, with both lines open and each one shut. No real issue - very minor bubbles in basket while the pump was on you could see clear through. when pump was shut off you could see a small bubble come up out of the line into the basket about every 4 seconds. pump never lost its prime. I figured it may be a small leak in the valve.
Now over the weekend - all of the sudden, there are lots of bubbles, cant see through the basket lid. If I turn the valve to close main line completely off (on skim only) - it is back to where it was (very small amount of bubbles). If I turn the skimmer line off - large amount of bubbles and it struggles to pull the water. And when pump is off large air bubbles up into the basket. no longer holds prime. The large bubbles stop if I close the main.
I am figuring a main line leak above teh water line and below the pump. So I need to know what and where and how to fix. I had the valve apart, lubed everything, i checked all abve ground connections, using the watertrick and no changes.
Thanks for any/all help.
